To all whom it mag/concern.

Be 1t known that LFERNANDO Srann Y XIMIENEZ, a citizen of the UnitedStates, re- 1 siding at New York, in the county of New York and State ofNewYork, have invented new and useful Improvements in Floating followingis a specification. V This invention relates to floating drydocks and jhas for its primaryobject'the construction of a dock of the characterset forthwhich shall be comparatively inexpensive to build, eflicientofoperation and particularly adaptedto the uses of such structures,

A further object of this invention is to provide a dock ofthe characterset forth with means. whereby the submerging and raising thereofmaybe'accomplished inthe most effective manner, preventing any side motionwhen submerging and securing at all times a stability. for the dock andthe vessel carried thereby.

A still further object of thisinvention is to construct a floating drydock. which can be readily transported to any desired location. I a IAnother ob ect: of the construction described herein is -the provisionofa floating dry-dock with means for controlling the raising andsubmerging movementsthereof in such a manner as to permitj o'f Y controlfrom specified points of thedock to enable the employment" of a minimumamount of seen, is of such a size as to accommodate afujlly equippedmachine shop, as well as operation to control themovement of the [clockI a 1 V "With the foregoing and other objects in f "view, as will fromtime to time appear hereinafter this invention consists in }the peculiararrangement and combination ofthe various cooperating elements of' afloating drydockas described inithe following specifi'cation and moreparticularly. pointed out in the appended claims.

Fig. 4 is a longitudinal section through one of the pontoons and,

Fig. 5 is asectio'n through one of the pontoon draining valves. I

6 designates va hollow pontoon preferably cylindrical and tapered at7'7. The base of they dry dock is formed by a plurality oflongitudinally extending strips 8; spaced apart and connected bytransverse strips 9 which support vertical members '10 carrymg a secondset of transverse str lps 11 adapted to connect a secondseries oflongitudinally extending strips 12, thus forming a plurality ofrectangular skeleton frames each one of which is adapted to incase andsupport a plurality of the pontoons 6 placed end to end in parallelseries across the enor open spaces between the tapered ends and alsobeverse frameworkstrips which carry the spontoons. v

At either side of the base are skeleton towers 13 extending up frombases 14 carried by the base frameworlgjthe towers 13 supporting a'machinerydeck 15 whichis reached from themaindeck 16 by astair-' way 17.This machinery deck, as will be the air compressors and pressure tanksfor framework-thus relieving the pressure against the dock bottomduringthesubmerging movement. ,7 t Each of the pontoons 6 comprises'acencompressed air for. use in operatingthe dock as will be hereinafterdescribed. i

The ipe 26 carries: on its 1 outer end a checkvalve 27 with which is connected one end of a pipe 28 which extendsupwardly through a 'casing'29 within to which is attached one end of apipe 3% extending through the casing 29 to the control house 80, whereit is provided with a blow off val e and a pressure gage 36. Adjacent tothe pipe 2G.the pontoon cylindrical section isequipped with an upperair-admitting and lower watendischarging valve device, illustratedlllClGliitll 1nF1g. 5. This dev1ce comprises a short cylinder 37extending inside the pontoon at an opening 38 therein, which is providedwith a flange 39 riveted to the pontoonshell, the rivets also passingthrough the flange of a collar l0 in order to fasten it to the outersurface of the pontoon shell about the opening 38 and on this collar isbolted by means of bolts i a cap 42 provided with central threadednipple d3. At suitable intervals about the cylinder 37 near its upperend'are provided relatively large ports e l, the interior of thecylinder37 being provided witha bushing containing a circumferentialseries of rel: c atively small ports 45 adapted to aline with the ports4:4. and uniformly spaced apart. A piston i6 is adapted to work withinthe eviinder 37 and is pro'vided with a stem 47 which extends nearly tothe bottom of the cylindrical portion of the pontoon and alincs with awater outlet opening 48 formed in the pontoon shell. On the piston rod4711821]:

A continuation 7 2 of the piston rod 4L7 is provided with ahead 73whichis coi'ifined in a recess formed in the bottom of the rod 47 by aflanged sleeve 73 bolted thereto at c5 74. 'This n1e1nber72 terminatesatits lower any suitable source."

end in avalve head 75 adapted to normally close upwardly against theseatao and provided with a depending cylindrical skirt 76 havingradially disposed ports 77' and an extension 78- guidingly engagedwithin the thimlole 70. f. V

Fromthe nipple L3 extends a vpipe-TE) which-passes upwardly through thecasing '29 to the control house 30, where said pipe is provided with acut-off valve 80 connecting'it with a connpressedair supply pipe 83.,which is supplied with compressed air from Adjacent the vent the pontoonis pro vided with a valve device represented as a whole by the numeral82 andbeing in every detail of construction similar to the one fromwhich the pipe 'Tllextends with the single exception that the cylinder34 thereoi is not provided with any ports 4%, do, so that no furth rdescription of this valve mechanism is necessary, it forming a waterinlet and pressure equalizing valve as hereinafter explained. Fromthevalve S2 tends a pipe 83 which extends upwardly through the casing 29to the control house 30, where it is provided with a out ell valve Setwhich connects it with a compre sed' air supplying pipe line Sfisuppliedby: any-suitable source of compressed air. V

The construction as abovedescribed is the same for each pontoom eachcontrol house receiving the. piping from a certain set of pontoons, asdiagraininatically' indicated in Fig. 3, the pipe lines 81. and 85 beingprovided. with. cut-oil valves 86 and "87 respectivelv, in order tocntirelycut off the supply of compressed air to the plurality of valves80 211M184, v The'operation of the construction above described is asfollows When it is desired to submerge the base deck, of a dock inorderto receive the vessel, the operators in the control houses 30 openthe valves 84" which. permits air from the compressed air supply pipe 85to'flow into the various pipes 83 to the respective valves 82, whereuponaction of the compressed air upon the piston 46 will cause the valve 75to be forced from its seat 55 against-the pressure of the wat s. andpermit water to flow upwardly and into the pontoon, through the opening48, the pipes 26 with their correspondmg gages 32--serv1ngto amdlcatc 1nthe control houses the pressure of the water i within the pontoon.Whcn'the dock has been submerged to the desired. level each valve 84:will be closed toprevent any further flow of compressed air,thuspermitting the valve- 82 to close under the pressure of the water,and the action of their springs 51, thus reseatingeaoh valve 7 5 againstits seat 55 and preventing any further entrance Of the water. V

The dock is now in position toreceive a vessel. I When is desired toraise the shown in detail in Fig' 5 and cause the piston to movedownwardly within the casing 45, which permits the compressed airto flowinto thepontoon through the apertures 45 and 44, and at the same timeunseats the valve '7 5 from its seat 55, as in the action described forthe other. valve 82. The pressure of the compressed air which is flowinginto the pontoon through the openings 45 and 44 will cause the watertherein to be forced downwardly and outwardly through the opening 48,the pressure valve in the pipe 26 indicating the pressure within thepontoon. When the desired level of the, dock has been reached the flowof air into the pontoon may be stopped by operat ing thevalves 80,whereupon the dock will float at the desired level. The air vents 33with their corresponding pipes 34 are controlled by means of valves 35and are sup plied with gages 36 in order to indicate the air pressurewithin the pontoon.

By the method of control above described the series of pontoons may beoperated simultaneously and submerge or lift the dock to any desiredlevel, the device indicating at all times the exact pressure of air andwater within the pontoons, so that a proper raising and lowering of thedock may be effected. In will'be further understood that upon theemptying actionof the pontoon the the water out.

watervwill also flow out through the valve device 82 in addition whenthe pressure overcomes the closing tendency of the spring 51, therebyexpediting the evacuation;

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is i 1. In a floatingdry dock, in combina tion,a main deck comprising a plurality of members spaced apart,separatepontoons carried in fixed position by said members in the spaces formedtherebetw'een, valves at the top and bottom of said pontoons, a

source of compressed air connected with the upper valves, andcontrolling means for opening the lower valves by means of com" pressedair to allow water toenter. the pontoon or to open both the upper andlower valves to force the water out of the pontoons by means of the airpressure.

2. Inna floating dry dock, in combination, a main deck comprising aplurality of members spaced apart to form a cratelike stru'cture, aplurality of separate pontoons carried in fixed position by saidstructure, a

machinery deck having a controllingtmeans, a main source ofcompressedalr controlled thereat, pipes leading therefrom to saidpontoons, and valves associated with each pontoon whereby on actuatlngsaid control ling means one valve in each pontoon is opened to permit aninflow of water or if filled with Water to admit compressed air to thepontoon through another valve to force FERNANDO swim) Y XIMENEa
